They have infinitely variable spindle rotation, table traverse and boring feed. An added exclusive SVN feature is electronic DUAL AXIS VARIABLE SPEED movement of the table. This allows the operator to position the workpiece with joystick controls on the control panel, dramatically reducing the effort required to center the spindle in cylinders for boring operation setup.
